Question: does the amount of tild or shift applied get recorded in the metadata or do you have to remember?

No, it does not get recorded in the metadata - tilt, shift, and rotation are purely mechanical and the settings are not transmitted to the camera. You have to remember, or write it down. The only -E (= electronic) part of the lens is the aperture control. As a side note there, even that can be 'broken' when you use a TS-E lens with an extender - they are compatible (although the TS-E manual indicates that extenders cannot be used), but the aperture data are improperly recorded in the EXIF header.

Yep. I have an 82mm B+W KÃ¤semann CPL (Slim mount, becuase I also use it on the 16-35mm II) that does very well on the TS-E 24mm II.

Thanks! I was a bit afraid there's going to be obvious vignetting with the 82mm filter.

This is one of those time where I wish there's special filter holders designed for the 17mm (something along the line of Lee's filter holder for the Nikkor 14-24). Having the option of using a filter really makes a difference...

Not much risk of that - the image circle of the new TS-E lenses (17mm and 24mm II) is huge! The only reason the hood fot the 24mm II is so short is that when you apply a lot of shift, you get vignetting (but then, you get vignetting on the side of the shift even with no filter or hood mounted). At shifts up to Â±8, there's no vignetting and no effect of adding a filter - even the CPL stacked on top of the MRC UV (F-Pro mount) is fine. Above Â±8, you start to see some shading - but removing the filters doesn't help significantly, so it seems to be an optical 'feature' of the lens.
